Software design evaluation plays an important role in software development process, to generate software product with high levels of productivity and efficiency. To achieve high level of qualitative software product, implementation of pattern can create a domain specific framework to provide consistency throughout a software solution. This paper proposed an evaluation pattern called Criteria Based Evaluation Pattern (CBEP) for measuring the Object-Oriented Design (OOD) model. First, the authors have identified some criteria and parameters by considering the design model. Then different metrics are proposed for each criteria and these metrics are used for measuring the design model.
